MACHINE FOR PUNCHING A JACQUARD-CARD.

Specification of Letters Patent.

Patented J' uly 2, 1907.

Application fue@ January 2,1907.` serai No. 350,325.

To all whom it may concern:

Be it known that I, FREDERICK G. LENTZ, a citizen of the United States, residing at Langhorne, Bucks county, Pennsylvania, have invented certain new and useful Improvements in Machines for Punching `lacquard-Cards, of which the following is a specifica tion. v

My invention relates to an improvement in machines for punching a jacquard card, and its object is to provide a machine of this character with means whereby a card may be punched to reproduce the design of a fabric directly from a previously woven fabric and without the necessity of first producing or making a card by hand.

Heretofore, insofar as I am aware, if a textile manufacturer desired to produce a fabric having or showing the design of a certain fabric as a sample, it was necessary for him to prepare first a drawing or picture of the same, from which a master card or cards would be produced by hand or manually. After' the manual production of such card or cards, they could be used in connection with a machine of known construction to occasion the rapid punching or reproduction of other cards.

By the use of my invention, Which I propose to attach to machines now known and in use for producing cards for jacquard machines, I am enabled to produce cards without the necessity of rst producing a drawing of the design which it is desired to reproduce and afterwards a master card, as stated.

My invention resides vin the combination and arrangement of parts as hereinafter described in detail in the specification, set forth and claimed in the claims, and as illustrated in the accompanying drawings forming a part of this specification, and by reference to which my invention may be more readily understood.

Figure l is a side elevation ofthe jacquard punching machine having my invention attached thereto;

p Figure 2 is a plan view of a portion of such machine, showing my invention attached thereto;

Figure 3 is a sectional elevation of the attachment embodying my invention; and

Figure/I is a plan view of a portion of my said invention.

In the drawings,-

l designates the main frame of my machine, and 2 designates a slidable frame secured upon the main frame l. 3 designates the driving shaft upon which is mounted the gear wheel 4, which meshes with a gear wheel 5 mounted upon the shaft 6. 7 designates aseries of jacquard cards which are adapted to travel through the machine. The-se cards travel over a roller 8, thence to what may be termed a sprocket bar l0 having lugs at its opposite ends, those at one end only being shown, and which are designated ll in Figure l of the drawings. These projections Il are adapted to register fed forward adistance sucient to bringa new card into,

position to be' punched.

In order to occasion periodic or step by step revolution of the sprocket bar l0, I have provided a small pinion l5 upon one end of the sprocket bar which engages a gear 16 which is rigidly connected to aratchet wheel 18, so that the gear wheel and the ratchet are adapted'to revolve together.

20 designates a lever mounted upon the pivot or journal of the gear I6 and ratchet I8, which lever is adapted to move independently of, the said gear and ratchet. Upon one end of the said lever a dog 2l is mounted, which is adapted to engage the teeth of the ratchet. The other end of the lever is provided with a slot 22 to movably receive a pin connected to one end of the link or rod 25, the other end of which is connected to one end of a lever arm 28 rigidly secured to one end of the shaft 6. The lever 28 rotates with the countershaft 6 in the direction indicated by the arrow 30 in Figure 1 and by reason of the pin and slot connection between the rod 25 and the lever 20, periodic movement of the ratchet 18 and gear 16 in the direction indicated by the arrow 3l is occasioned. Such movement of the gear 16 occasions step by step revolution of the gear l5 in the opposite direction, whereby the jacquard cards are fed through the machine step by step. 32

designates a fan-shaped projection or extension of the lever 28 which is provided with a concentric slot 33 through which a pin 34 projects. The lever 28 may be adjusted to different positions and clamped by means of a nut 35.

36 designates an eccentric upon the countershaft 6 and 37 designates an eccentric rod which is connected to the arm of a rock bar or shaft 38, on which are supported slotted arms, one of which is indicated by dotted lines at 40, which slotted arms are adapted to engage centering pins, one of Which 4l is shown in Figure I of Vthe drawings. The purpose of these pins is to engage the opposite ends of each of the jacquard cards, so as to hold the same in proper position while it is being punched by the punches 42, shown in Figure l.

The operation of the machine is so timed that immediately after a quarter revolution of the sprocket bar l1, the high portion of the wheel cam 44 is located immediately underneath the standard 45, the top portion of which is connected to what may be termed a punch bar 46. The punch bar is thus raised so as to force or lift the same upwardly to bring the cards into contact with the lower ends of the punches 42, whereby holes corresponding to a certain pattern may be punched in the said cards. The cam wheel 44 is mounted upona shaft 48 which is driven b'y a gear mechanism indicated at l 49. The machine is started by the depression of a lever punches 42 project.

vto occasion the perforation o-the cards.

50 which is connected by means of a cord 5l to a lever 52 which controls mechanism (not shown) by means o which the machine may be driven or operated. Movement of the slidable frame 2 is occasioned by means of lever arms 55 which engage at their upper ends pins 56 upon the sides of the said frame. The lever arms 55 are connected to a rock shaft 58 which is rocked by means of a lever 59, one end of which is connected to the said rock shaft 58, and the other o which is provided with a cam roll 60, which is adapted to engage a cam (not shown) in the side of the gear wheel 5 shown in Figure 2.

When the punch bar 46 is moved upwardly, the cards come into contact with the lower ends of the punches 42, as has been stated, with the result that all o the punches which are at such time held against upward movement perforate the cards, while those punches which are permitted to move upwardly, due to their contact with the cards, do not periorate such cards. The operation oi the punches is controlled by a series of plugs, one oi which is indicated in dotted lines at 6l in Figure l. It will be noted that this plug is located near the upper end of one oi the punches so that upward movement of the punch is prevented, with the result that ii the card is moved upwardly against this punch, a hole will be orced through the same.

It will be understood that the punch bar 46 is provided with periorations into which the lower ends of the Each of the plugs 6l is connected to a bar or needle 62. Each of these bars or needles is connected to the lower end oi a pivoted lever 63. The upper end oi each oi the levers 63 is connected to a bar or needle 64 similar to the bars or needles 62.

It will be understood that there are a large number of these bars or needles 62 and 64 and that a movement of any one othe bars or needles 64 in one direction occasions a movement of a corresponding bar or needle 62 in the opposite direction. A movement, or instance, of the bar or needle indicated in dotted lines at 64 in Figure l to the right would occasion a movement of the bar or needle indicated by dotted lines at 62 in the same figure, to the left, so as to withdraw the plug 6l from its position over the upper end oi the punch shown in part in dotted lines in Figure l, in which case such punch would be permitted to move upwardly so as not The bars or needles 64 are mounted in a stationary frame which, however, is not shown.l

and 7l designate the side members of a frame in which a series of plugs 72 is mounted, which plugs extend transversely of the members 70 and 71, as indicated. '73 designates end pieces connected to the side members 70 and 7l o the frame and 74 designates journals connected to the end pieces 7 3 and which rest in bearings 75 at the opposite sides of the machine, such bearings being supported upon arms which extend orwardly from the frame 2.

76 designates U-shaped springs which are secured to the frame 2, and which bear against one side ot the frame which supports the plugs 72, so as to prevent the same from rotating in its bearings 75. Each of the plugs 72 is located or positioned in alinement with a bar or needle 64. 77 designates coiled springs which are connected respectively to plugs 72 and coil around the same, as indicated very clearly in Figures 2 and 3.

The purpose o these springs is to hold the plugs nor mally in the position indicated in Figure 2 of the drawings, with both ends projecting beyond the sides o the frame.

The plugs 72 are connected by means oi harness threads 80 to what I term harness plates 8l, which are arranged side by side and very close together, as indicated in Figure 2, o the drawings. 'lhese plates are provided upon their lower edges with semi-circular notches, as indicated at 82 in Figure 3 ol the drawings, and said plates rest upon a rod 83, which rod lits in the said notches. The rod 83 is supported at its opposite ends in horizontal slots 84 in supports S5. As illustrated, these supports extend up from the lloor, but it will be understood that they may be supported in any other suitable manner, as, lor instance, upon the iranie of the machine.

The rod 83 is adapted to be moved back and orth in the slots 84 by means ol connecting links 86, which are connected to the rockinglevers 55, 88 designates hooks upon the outer or iront ends ol the harness plates 8l, which are adapted to engage with a stop plate or bar 90 supported at its opposite ends in any suitable manner and in proper relation to the harness plates 8l to be en gaged thereby when such plates are elevated. As illustrated in the accompanying drawings, said stop plate or bar is supported upon the upper ends of the supports 85.

92 designates harness threads which are connected to the outer or iront ends ol the harness plates 8l, which harness threads are adapted to be connected to the inner ends of the warp threads of a fabric, the design oi which it is desired to reproduce.

Broadly considered, the idea of my invention is that each of the weit threads or fillers shall be moved singly bodily rearwardly to a point directly in iront oi the ends of the harness plates 8l, after which, such weit thread as has been so moved is lifted up so as to raise or elevate all of the harness plates which are connected to warp threads which are located above such weft thread.

In practice, it is found desirable, however, to attach a needle or wire to the weit thread and draw such needle or wire through the fabric to take the place ol the weft thread, for the reason that it may happen that the weft thread would not always be of sullicicnt strength to insure the raising ol the harness plates 8l connected to threads occupying a position above the weft thread. A portion of such wire or needle is shown at 95 in Figure 2 and in section or end view in Figure 3. When such wire or weft thread, as the case may be, is lifted, as indicated in Figure 3, certain of the harness plates are elevated, so as to bring the hooks 88 into engagement with the stop bar or member 90. Immediately after these harness plates have been raised, as indicated, the starting lever 5() is depressed, Y.

so that the operation of the machine may begin, the result being that the cards are moved forward a step in the machine for each cycle or revolution oi the parts, and at the same time the shaft 58 is rocked so that a complete oscillation ol the lrame 2 is occasioned, the oscillation of such frame being occasioned by the lever arms 55. All the harness plates 8l which are in engagement with the stop bar or member 90 are held stationary, while those which remain in engagement. with the rod 83 are oscillated or moved in unison with the frame 2, as also are the plugs to which they are connected.

These plugs, which are connected by means of harness threads to the harness plates which remain in engagement with the rod 83, move rearwardly, while those which are connected with the harness plates which have been moved into engagement with the stop plate or member 90 are held in their original position, the result being that there is relative movement between such plugs and the frame, so as to compress the coiled springs surrounding such plugs. This is indicated in Figure 3 of the drawings. i

All of the plugs which move rearwardly with the frame 2 and the plug frame connected thereto engage the forward ends of the bars or needles 64 which are in alinement therewith, so as to push the same rearwardly, as indicated in Figure 3 of the drawings` The movement of these rods or needles rearwardly occasions pivotal movement of the levers 63 connected to them and a consequent forward movement of the corresponding bars or needles 62, and the punch controlling plugs 6l, which are connected to the latter bars or needles.

lt will thus be seen that those of the plugs 6l which are not moved forward to a position out of alinement with the punches 42 are those which correspond to the harness plates 81, which are in engagement with the stop bar or plate 90, and which plates have been raised into their position of engagement with such stop plate or member by means of those of the warp threads which occupy a position above the weft thread or wire which has been moved forward and elevated, as described.

In this manner, I am enabled to punch the cards so that when employed in the weaving of a fabric they will occasion the reproduction of the design of the fabric which it is sought to reproduce, it being only necessary to employ the different colored threads which are necessary to the production of such design.

Having thus described my invention, I claim:-
